Title (EN) SPEECH RECOGNITION METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE RECONNAISSANCE DE PAROLE
(ZH) 语音识别方法和装置
Abstract:
(EN) A speech recognition method and device. The speech recognition method comprises: obtaining features of a speech signal to be recognized (S11); performing, according to the features, path search in a search space generated by composition, and outputting a decoded result (S12); determining whether recognition rejection is required or not according to the decoded result (S13); and determining that the speech recognition result is recognition rejection if recognition rejection is required, and obtaining the speech recognition result according to the decoded result if recognition rejection is not required (S14). The method has a good recognition rejection effect.
(FR) La présente invention concerne un procédé et un dispositif de reconnaissance de parole. Le procédé de reconnaissance de parole comprend : l’obtention de caractéristiques d’un signal de parole devant être reconnu (S11) ; la conduite, en fonction des caractéristiques, d’une recherche de trajet dans un espace de recherche généré par composition, et la délivrance en sortie d’un résultat décodé (S12) ; la détermination du fait que qu’un rejet de reconnaissance est requis ou non en fonction du résultat décodé (S13) ; et la détermination du fait que le résultat de reconnaissance de parole est un rejet de reconnaissance si le rejet de reconnaissance est requis, et l’obtention du résultat de reconnaissance de parole en fonction du résultat décodé si un rejet de reconnaissance n’est pas requis (S14). Le procédé présente un bon effet de rejet de reconnaissance.
(ZH) 一种语音识别方法和装置,该语音识别方法包括:获取待识别的语音信号的特征(S11);根据所述特征在构图生成的搜索空间内进行路径搜索,输出解码结果(S12);根据所述解码结果判断是否需要拒识(S13);如果需要拒识,则确定语音识别结果是拒识,如果不需要拒识,则根据所述解码结果获取语音识别结果(S14)。该方法具有很好的拒识效果。
